WATCH-REGULATO R.

SPECIFICATION forming part of Letters Patent No. 318,208, dated May 19,1885.

(No model.)

To (tZZ whom it may concern:

Be it known that I, SwEN P. SANDMARK, of Ishpeming, in the county of Marquette and State of Michigan, have invented a new and Improved \Vatch-Regulator, of which the following is a full, clear, and exact description.

The invention consists of the combinations of parts and their construction, substantially as hereinafter fully set forth and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view in enlarged size of a watch plate and regulator with myimprovements. Fig. 2 is a cross-section on theline so 00, Fig. 1. Fig. 3 represents the adjustingscrew in larger size, one head being in section.

The ring or collar a is provided with indexarms I), and mounted upon the bridge 0, all as usual. Upon the bridge 0 is attached a light frame, d, of fork shape, and through the forked ends of this frame passes the screw 6, having a slotted head of the usual character upon one of its ends, and fitted at the opposite end with a sleeve or collar, f, which is slotted, so as to form a head at that end also, and the two heads, taking against the forks of the frame, prevent any end movement of the screw.

5/ is a slide fixed upon the screw having its inner end slotted or split to pass upon the lug or projection h of the ring a.

Across the franie d is a cross bar or pin, 2', that extends loosely through the end of the slide-piece g,s0 as to form aguide therefor and prevent any tipping or side movement of the slide-piece when itismoved by the screw. By turning the screw 6 thepiecegis movedin one direction or the other in a straight line, and by its engagement with the lug It causes the movement of the ring a and arm I), which are connected with the balance-spring in the usual manner. The connection between the piece 9 and the ring a not being rigid, the slidepiece is free to move in a line parallel with the screw, and at the same time give the necessary movement to the regulator.

This device is ornamental, besides being more reliable for fine adjustment than when the movement is given in one direction by a spring, as is usually the case.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. In a regulator for watches, the combina tion, With the ring of the regulator having a lug, of the split slide-piece, and the forked frame having the screw with heads bearing upon said frame, substantially as and for the purpose set forth.

2. In a watclrregulator, the combination of theforked frame d, the cross-bar i, the doubleheaded screw 0, and the slide 9, substantially as shown and described.
